The driver 23 outputs a display drive signal based on the display data output from the control unit 14 to the LCD display unit 11. The LCD display section 11 displays the measured pressure, the current time, and the like.

Next, the operation of the above embodiment will be described with reference to FIG. 8 and FIG. FIG. 8 is a flowchart showing the overall operation, and FIG. 9 is a flowchart showing the operation of the data storage processing in FIG.

Time display mode In the case of "M = 0", that is, the time display mode, the control unit 14 is in the HALT state of step A1 until the clock signal is output from the frequency division / timing signal generation circuit 22. When the clock signal is output, it is determined in step A1 that the clock signal is present, and the process proceeds to step A2. In the current time clocking process of step A2, the current time data stored in the clock register is updated. Next, in step A3, it is determined whether or not "M = 1", that is, whether or not the content of the mode register M is "1".
If YES is determined in step A3, the process proceeds to step A4, and if NO, the process proceeds to step A8. Now, since “M = 0”, the determination is NO, and the process proceeds to step A8.

In step A8, it is determined whether or not “M = 2, F ₁ = 1”, that is, whether or not the motion measurement mode is being performed and the motion measurement is being performed.
If YES is determined in this step A8, the process proceeds to step A9, but if NO, the process proceeds to step A10. Now, "M = 0"
Is determined as NO, and the process proceeds to Step A10. In the display processing of step A10, "M = 0" is determined, and the current time data "10-23 10:35" stored in the clock register is determined.
56 (10:35:56 on October 23) "is displayed as shown in FIG. 10A. After executing step A10, the process returns to step A1.

Optimal pressure setting mode Here, a procedure for adjusting the air pressure in the gas tanks 6, 7 to the optimal pressure will be described. In this case, first enter the switch S ₁ to set an optimum pressure setting mode "M = 1". Then, to start the pressure measurement by entering the switch S _2, LCD display 1
While checking the pressure data displayed in 1, air is injected into the gas tanks 6, 7 by the air pump. Then, when it is optimum support state, in which to store the current pressure data in the register D ₁ enter the switch S _3.

That is, when the input switch S _1, it is determined that there is the switch input, the processing proceeds to step A11 in step A1. Step A
Switch input at 11 whether the switch S ₁ is being determined. In this case, the switch S ₁ is entered is determined YES, the process advances to the step A12. In step A12, the content of the mode register M is incremented by 1 to "M = 1", and the optimum pressure setting mode is set. After step A12, the process proceeds to the display process of step A10, an optimum pressure data stored in the register D ₁ as shown in "M = 1" determination to example 10 Figure B to "1.90 (kg)" registers The current measured pressure data “1.45 (kg)” stored in D ₀ is displayed.

Thus, to enter the switch S ₂ to start the pressure measurement. Like the above, the flow advances from step A1 to step A11, the switch S ₂ in step A11 is input is determined to NO, the process proceeds to step A13.

In step A13, the inputted switch whether the switch S ₂ is determined. Now, the switch S ₂ is input is determined to be YES the flow proceeds to step A14.

In step A14, it is determined whether "M = 1" as in step A3. If YES is determined in this step A14, the process proceeds to step A15, and if NO, the process proceeds to step A16.
Now, since "M = 1", the answer is YES and the process proceeds to step A15.

In step A15 the contents of the flag register F ₀ is inverted. Now, since the flag register F ₀ is “0” in the initial state, it is inverted to “F ₀ = 1” and the pressure measurement flag is set. After the execution of step A15, the process proceeds to step A10. Thereafter, the HALT state is maintained until the timing of the timing is reached.

In the above-described state, it is assumed that timing is reached when pressure is injected by the air pump. In the same manner as described above, the process proceeds to steps A1 to A3, where "M =
1 "so that the answer is YES and the process proceeds to step A4.

In step A4, the content of the flag register F ₀ is "1" or not is determined. In this case, step A15 is executed and “F ₀ = 1”, so that the determination is YES and the process proceeds to step A5. In step A5, the content of the register C is incremented by 1, and the pressure measurement interval time is measured.

In the next step A6, it is determined whether or not the content of the register C is a value corresponding to "5 seconds". That is, in this embodiment, the interval time is measured by the register C in order to measure the pressure every 5 seconds. If “5 seconds” has not elapsed and NO is determined in step A6, step A1 is executed.
Returning to step A1 via 0, step A1
Steps A6 and A10 are repeatedly executed. When the content of the register C reaches a value corresponding to "5 seconds", YES is determined in step A6.
And proceed to step A7.

In step A7, the pressure in the gas tanks 6, 7 is
5 is measured and stored pressure data obtained in the register D _0. That is, the control unit 14 outputs a signal “a” of “1” level to the sensor unit 15 and the A / D converter 16 to operate them. As a result, the sensor voltage output from the sensor unit 15 is A / D
Input to converter 16. Then, the sensor voltage is converted into a digital signal by the A / D converter 16 and input to the control unit 14. Controller 14 stores the digital signal input from the A / D converter 16 in the register D ₀ of RAM 17. From step A7 proceeds to display processing in step A10, the current stored in the register D ₁ as shown in FIG. 10 C optimum pressure data "1.
90 and (kg) ", the current measured pressure data, for example, stored in the register D ₀ is" 2.12 (kg) "is displayed.

Here, the air pressure in the gas tank 6, 7 or or or disconnect injecting air, when it is just good state to support the foot, enter the switch S _3.

As a result, the process proceeds from step A1 to step A11, and in steps A11 and A13, each is determined to be NO, and the process proceeds to step A18. In step A18, the input switch is switch S
₃ is determined. Now, the switch S ₃ is input is determined to be YES the flow proceeds to step A19.

In step A19, it is determined whether or not "M = 1". Now, since "M = 1", the answer is YES and the process proceeds to step A20. In step A20, the content of the register D ₀ is stored in the register D ₁ as the optimum pressure data, step A1
Go to 0. As a result, new optimal pressure data is stored in the memory.

Movement measuring mode also running high jump, the movement of such jump run width, if measuring the depression intensity and duration of every second of the approach section are stored in the memory, the motion measurement mode by entering the switch S ₁ To As a result, the process proceeds from step A1 to step A11, and YES is determined. At step A12, the content of the mode register M is incremented by 1 to "M = 2", and the exercise measurement mode is set.

Then, to start the motion measurement by entering the switch S _2.
In the same manner as described above, the process proceeds to steps A1, A11, A13, A14, and A16. In step A16, it is determined whether or not “M = 2”. . In this exercise measurement start / stop processing,
The contents of the flag register F ₁ is inverted from "0" to "1". After the execution of step A17, the process proceeds to the display process of step A10, and as shown in FIG.
T! "Is displayed.

Thereafter, since “M = 2, F ₁ = 1” and the motion measurement is started, the flow proceeds to the motion measurement process from step A3, A8 to step A9 every time the timing is reached. That is, the exercise measurement process is executed at each sampling timing of 32 Hz.

In the motion measurement process, pressure data in the gas tanks 6 and 7 is measured by the sensor unit 15 and sequentially stored in the RAM 18. Therefore, the pressure data is sampled in synchronization with the timing of 32 Hz and stored in the RAM 18.

Then, when the first trial of the high jump and the long jump is completed and the exercise measurement is to be terminated,
To enter the S _2. Then, the process proceeds to steps A1, A2, A13, A14, A16, motion measurement start-stop processing in step A17 and YES is determined in step A16 is executed again, "0" the content of the flag register F ₁ from "1" And the motion measurement is completed. After the execution of step A17, the process proceeds to step A10.

Then enter the switch S _3, based on the pressure data stored in the RAM 18, performs data storage processing for calculating the respective data of the depression intensity and duration of each step in the approach section. Thereby, the process proceeds from step A1 to step A11,
In steps A11 and A13, respectively, it is determined to be NO, and the process proceeds to step A18. In step A18, the switch S ₃ is input is determined to be YES the flow proceeds to step A19. Step A19
Then, it is determined whether or not “M = 1”, but since “M = 2”, the determination is NO and the process proceeds to step A21. In step A21, it is determined whether or not "M = 2". In this case, the determination is YES, and the process proceeds to the data storage process in step A22.

Details of the data storage processing will be described with reference to FIG. First,
In step B1, an address pointer (not shown) of the RAM 18 is initialized. That is, the pointer is initialized and the start address of the RAM 18 is designated. Next, in step B2, pressure data is read from the RAM 18 based on the designation of the pointer, and in step B3, the content of the register C is incremented by one. The register C is a register for measuring a required time for each step.

In the following step B4, it is determined whether or not the content of the register L is "1". Now, since the content of the register L is "0", it is determined to be NO and the process proceeds to step B10.

In step B10, in order to detect the pressure data during depression in walking, whether read pressure data is greater than 1.5 times the content of the register D ₁ (ie optimum pressure data) is determined. If YES is determined in step B10, the process proceeds to step B11, and if NO, step B13 is performed.
Proceed to. In this case, if the pressure data is not the pressure data at the time of stepping in walking, the size is about the optimum pressure data, so that the determination is NO and the process proceeds to step B13. Step B13
Then, the content of the pointer is updated, and the next pressure data in the RAM 18 is designated.

In step B14, it is determined whether or not the content of the pointer P specifies the last address of the RAM 18. Now, since the final address has not been reached, it is judged NO and the step
Return to B2.

Hereinafter, until step S10 is determined to be YES, step
B2 to B4, B10 and B13 are repeatedly executed.

Then, when the pressure data larger than 1.5 times the optimum pressure data, that is, the pressure data at the time of stepping is read from the RAM 18, it is determined as YES in step B10, and the process proceeds to step B11. In step B11, "1" is written into the register L, and the fact that the pressure data at the time of stepping is read is stored. In step B12, the read pressure data is temporarily stored in the work area (not shown) of the RAM 17 together with the contents of the register C. Hereinafter, the process returns to step B2 via steps B12, B13, and B14.

Similarly to the above, when Steps B2 and B3 are executed and the process proceeds to Step B4, since "L = 1", it is determined as YES and Step B5 is executed. At step B5, the content of the register S is incremented by one, and the time for comparing the pressure data within a predetermined range (0.5 seconds) is measured. Next steps
At B6, it is determined whether or not the content of the register S is a value corresponding to 0.5 seconds. In step B6, if YES, the process proceeds to step B7, and if NO, the process proceeds to step B12.

Hereinafter, steps B2 to B6 and B12 to B14 are repeatedly executed as described above until YES is determined in step B6, that is, until the content of the register S reaches 0.5 seconds, and the pressure data and the content of the register C are It is temporarily stored in the work area. Then, the content of the register S becomes 0.5 seconds,
If YES is determined in step B6, the process proceeds to step B7.

In step B7, each pressure data stored in the work area is compared, and the highest pressure data among them, for example, `` 3.
45 (kg) ". In step B8, the time data indicating the required time between each depression stored in the register C is corrected based on the time data of the maximum pressure data. Then, the maximum pressure data “3.45 (kg)” and the time data are written into the exercise data memory 17a of the RAM 18 as “first step data”. In this case, the time data is “0” because it is the first step.

In the following step B9, "0" is written into the registers S and L, respectively, and cleared, and the process proceeds to step B13. Similarly, the address is updated in step B13, and if it is determined in step B14 that the address is not the final address, the process proceeds to step B2.

As described above, in step B2, pressure data is read from the RAM 18 based on the designation of the pointer P, and in step B3, the register C is incremented by one.

At step B4, it is determined whether or not "L = 1", as described above. Since "L = 0" now, the result is NO, and step B10 is performed.
Proceed to. In step B10, similarly to the above, it is determined whether or not the read pressure data is the pressure data at the time of stepping (second step).
Steps B2 to B4, B10, and B13 are repeatedly executed, and pressure data at the time of stepping is searched.

Then, when the pressure data at the time of stepping on (the second step) is read from the RAM 18, it is determined to be YES in step B10, and the process proceeds to steps B11 and B12. Similarly, pressure data in a predetermined range (0.5 seconds) is temporarily stored in the work area until YES is determined in step B6. Then, in step B7, the maximum pressure data of the second step, for example, "3.56 (kg)" is searched. In step B8, the time data in the register C is corrected, and the maximum pressure data "3.56 (kg)" and the time data "0.63 (second)" are stored in the motion data memory 1 of the RAM 18.
7a is written as “second step data”.

Hereinafter, the same applies to the third and subsequent steps. Then, the pointer is updated to the final address, and step B14
If the answer is YES in this step, the data storage process ends, and the process proceeds to step A10.

In this way, for example, when the first try is performed in a running high jump and the pressure and time data at that time clears a height of, for example, 1.70 m when stored in the memory 17a, for example, the exercise data memory Numerical data “1.70 (m)” is added to the first exercise data stored in 17a
Can be added. In this case, the numerical data "1.70" is inputted by operating the numerical key of the keyboard 12 at the digit where the cursor indicating the data input wait shown in FIG. This allows the step
From A1, proceed to steps A11, A13, A18, A24, and in step A24
The numerical data “1.70” input in step A23 determined as NO is stored in the input data area of the exercise memory 17a of the RAM 17.

Finally, a case where the exercise data stored in the RAM 17 is sequentially displayed will be described. In this case, motion measurement mode shown in M = 2 in FIG. 10, inputs the switch S _4. Thereby, the process proceeds from step A1 to steps A11, A13, A18, A24,
YES is determined in step A24, and the process proceeds to step A25. In step A25, it is determined whether or not "M = 2", and the determination is YES, and the process proceeds to step A26.

In the display data updating process of step A26, the switch S ₄
Every time is operated, the address pointer P of the RAM 17 is updated, for example, from the exercise data memory 17a, the first step pressure data 3.45 kg (FIG. 10F) and the second step pressure data "3.56 (k
g) and time data "0.63 (seconds)" are read out and displayed as shown in FIG. 11A.

Still enter switch S _4, step in the same manner as described above
A26 is executed, and the pressure data “3.90 (kg)” and the time data “0.69 (second)” of the third step are obtained from the exercise data memory 17a.
Is read out and displayed as shown in FIG. 11B.

Hereinafter, As you type the switch S _4, 4 step th appears 5 step th data, finally, as shown in FIG. 11 C, numerical data "1.70 (m) that was set in the input data area "
Is displayed.

In this state, when the input switch S _4, 11 motion data memory 17b of the RAM17 in the second try, as shown in Figure D
, The pressure data "2.97 (kg)" and the time data "0 (second)" of the first step are displayed.
